Abstract:
(EN) A solid electrolyte according to the present invention comprises: a high-density electrolyte layer comprising a NASICON material; and a porous structure layer integrally layered on at least one surface of both surfaces of the high-density electrolyte layer, comprising the NASICON material, and being thicker and having a greater porosity than the high-density electrolyte layer. Therefore, the high-density electrolyte layer can be thinly formed, and necessary mechanical strength can be obtained by means of the porous structure layer, and thus sodium ion transfer performance can be remarkably improved in comparison to when only the high-density electrolyte layer is thickly formed alone, and, as a result, the output and the performance of a sea water battery can be improved. The solid electrolyte of the present invention can be variously used as a solid electrolyte of a sea water battery, and the like.
(FR) La présente invention concerne un électrolyte solide comprenant : une couche d'électrolyte à haute densité comprenant un matériau NASICON; et une couche de structure poreuse stratifiée d'un seul tenant sur au moins une surface des deux surfaces de la couche d'électrolyte à haute densité comprenant le matériau NASICON, et qui est plus épaisse et dont la porosité est supérieure à celle de la couche d'électrolyte à haute densité. Par conséquent, la couche d'électrolyte à haute densité peut être formée mince et la résistance mécanique requise peut être obtenue au moyen de la couche de structure poreuse, et ainsi, la performance de transfert d'ions sodium peut être remarquablement améliorée par comparaison à lorsque la couche d'électrolyte à haute densité est formée épaisse indépendamment, d'où une amélioration de la sortie et des performances d'une batterie à eau salée. L'électrolyte solide de la présente invention peut être utilisé de diverses manières en tant qu'électrolyte solide d'une batterie à eau salée, et analogue.
(KO) 본 발명에 따른 고체 전해질은, 나시콘(NASICON) 물질을 포함하는 고밀도 전해질층과, 상기 고밀도 전해질층 양면 중 적어도 어느 한쪽 면에 일체로 적층되며, 상기 나시콘 물질을 포함하되, 상기 고밀도 전해질층 보다는 두께가 두껍고 공극률이 큰 다공성 구조층을 포함하는 고체 전해질을 포함한다. 따라서, 고밀도 전해질층을 얇게 형성하고 아울러 다공성 구조층에 의해 필요한 기계적 강도를 갖출 수 있기 때문에 고밀도 전해질층만을 단독으로 두껍게 형성한 경우와 비교하여 나트륨 이온의 전달 성능이 월등히 향상될 수 있고, 그 결과 해수전지의 출력, 성능이 향상될 수 있다. 본 발명의 고체 전해질은 해수전지의 고체 전해질 등으로 다양하게 이용될 수 있다.
